He's being held without bond, but a detention hearing is set for Tuesday.

Trial is scheduled for July 2. Kurbanov communicated in court through a Russian interperter, his defense attorney said.

Officials say Kurbanov, was living legally in Boise at the time of his arrest.

Kurbanov allegedly worked with unnamed co-conspirators to provide support, software resources and money to the Islamic Movement of Uzbekistan - a designated foreign terrorist, the U.S. Attorney's Office says.

The raid of the apartment in the Boise neighborhood took many by surprise.

"It was like terror in the air when people start seeing this sort of thing (in this neighborhood)," said Jasyn Fairchild, a student at nearby Borah High School.

Another woman who is a caretaker in the same complex was surprised to see federal agents in full protective coveralls. She was even more shocked when she found out it was in regards to a terrorism investigation.

"Coming to work I saw it all and I thought it was a meth lab is what I thought," said Danelle Soderling.

A federal grand jury in Boise returned a three-count indictment charging Kurbanov with:

1) One count of conspiracy to provide material support to a designated foreign terrorist organization,

2) one count of conspiracy to provide material support to terrorists and

3) one count of possessing an unregistered destructive device.

According to the indictment, the parts of the device were a hollow hand grenade, hobby fuse, aluminum powder, potassium nitrate and sulfur.

If convicted on the Idaho charges, Kurbanov faces a maximum of 15 years in prison on each of the conspiracy counts and 10 years in prison on the possession of an unregistered destructive device count.

“Today’s arrest and these indictments underscore our commitment to aggressively and thoroughly investigate those who conspire to engage in unlawful terrorist activities,” said Wendy Olson, U.S. Attorney.

Earlier this year, federal authorities say Kurbanov taught how to make explosive devices and distributed information relating to the manufacture and use of an explosive or weapon of mass destruction through Internet videos.

He's also alleged to have conducted instructional shopping trips, provided written recipes and gave verbal instructions on where to buy the necessary supplies.

Kurbanov has a fairly clean record in the Gem State. Court records indicate he's only been cited for two instances of speeding and one time for driving without insurance.
